According to Darwin, humans have evolved from apes. I want to know why some apes evolved into humans, why not all evolved? Why apes today are not evolving into human? similarly, why are lower animals and plants not evolving into higher animals and plants?

There's no such thing as a "lower" or "higher" organism. Each has evolved to fit a particular niche in its environment. For example, most apes today live in heavily forested habitats, whereas humans originally evolved to live in plains areas.

Generally speaking, the more people talk about "being saved," the further away they actually are from true salvation.

1. Darwin did not claim humans evolved "from" apes. Have you read any of Darwin's actual works? Ever hear the term, common descent?

2. Assume we're talking about amphibians going from a wet swamp to a dryer land environment. Do they become more reptile like? Well yes and no. Yes in that toads do have leathery skin. Could they also gain a kidney that produces uric acid? Maybe.

But the point is, if you had a toad that had all the characteristics of a reptilian crocodile, it would still not be one. Classification is based on cladistics(origins). Read up on convergent evolution.

So this mean if today, apes start to live in plain areas, they will surely evolve into humans...?

Highly unlikely since humans already occupy that ecological niche. If apes started living in plains, they might adapt to it differently from how our human ancestors did and evolve into something completely different. Or they might be outcompeted and driven into extinction by the humans already living there. It's hard to say since so much of evolution depends on random chance.

It seems that it's a common misinterpretation that evolution creates a higher organism. Besides the confusion between apes and humans are still mystefied by what really is the missing link that had diverged. The evidence would just probably rely on the explanation about the common descent that mith just replied

Nowhere did Darwin say that humans decended from apes (impllying that apes changed into humans)! Remember that evolution does not deal with individuals but with the entire population.What evolution teaches us is that organisms change over time and moderan day apes have a common ancester as humans. That is not quite the same thing.
